Bc it known that l, Lizox i. Lows, ii citizen of the liiitcd Sintes,residing zit Sen .lfriinciscin in the count),v of Sun Francisco undStute of California, have invented certain new :ind useful improvementsin GaslJuiii'iei-s, of which the following is a speciicw tion.

The object ol this invention is to provide s.

giis-purilicr ol' chciip and siinple construction which will be moreeffective in its use thun those heretofore oinploied. f

in the iicooinpiinying drawings, ligure l is n verticiii section ol thepurifier. enlarged broken perspcc the ports thereof.

Referring to the drawings, 1 represents the tive View of one of whencooling. The masses of oxid of iron are 'thus forced through theintcrsticcs between the masses of oxid of iron so moving retard thesurfaces in actual contact with tliein, while the material out ofcontact cnn more iiiorc freely. This expension'and contraction thereforetend to continually break up these iinisses und prevent them iissuniingn compact permanent forni. The motion of the oxid of iron itself, due tochanges of temperature, is thus utilized to counteract any tendene-y ofthe oxid ol" iron to forni. impervious Fig. 2 is :in

messes, and thus the iiiiiterinl is used eiTect- Wely for thepurification of gus .without the usuel labor incident to changingpurifiers, its

j at present.

casing of the purilici', provide-d iit tlietop with n removable lid .2.

The gais to be purilicd enters bi' the inlet 3 nt the bottoni andcscnpes by the outlet 4 at the top. nso doing it passes through nizisses5 oi oxid of iron, which eil'ect the puriliciitioii of the gus in theniiiiiiiei well known in the urt.

The l present invention resides in the previsioni being here shown foursuch trays superposedv upon each other und the lowerriiost troyresting'upoii e. suitable support TJ. In trie bottom of the tray islorini d u grating 8 of oars suicientiy 4close together to prevent theoxid of iron felling through. Above seid bers are two rows of bars 9,extending persk lei with timbers 8 of tire grating, but further spartfrom auch Esch tray or boi; is supplied wit-.be sucient quantity of omoof iron: i

Owing; to repented changes of temperature, dueto the intermittentpassage of the hosted gas and the chemical changes which take place, theoxid of ironie in continual motion, extending when iiot und againcontracting iorous forni, lifter u certain boxes to contain the oxid ofiron, since these trays cnn with greater ease be removed sep eretely forthe purpose of changing the nis-f teriai or for other purposes.

I ciaiin- 1. A gas-puriiicr lowing un inlet and en outlet for the gas tobe purified und provided with n series of trays or boxes between seidinlet und outlet, euch box being provided with ineiins for support-ingthe purifyin nntteriiil while allowing the gais to escape t ere through,und being nlso provided with Sta# tionnry biirs extending into` thepurifyiliig iiiziteruil to disintegrate the siiiio by the niio` tion dueto changes of teii'iperiiture,substzinffA tiiilly es idescribed..

2. '584B- lLll el.' hvino' all inlet Sind all b p lp outlet for the gasto be purified and provided with n series of trays or boxes between saidinlet und outlet, each box being providedy with ineens for supportingthepurifyinenmf' terisl while allowing thegas to escape t erethro'ugi, andbeing also provided with'a lu-v' rslity of rows of stationary bars extening into the purifing material to disintegrate t motion due tochanges ofthe saine by e temperature, substantially iis described.

In witness whereof I have hereunto set my i the'upper bars 9, which barsby contact with y if@ Wlule not absolutely necessary, it is pref`creible Vto provide e plurality of trays or,

hand in the presence of two subscribing,r witmesses.
